WILLIAM I-I. HARIVION, OF CHICAGO, ILLINOIS.

WATCH-GUARD.

Application filed March 26, 1913.

To all whom t may concern Be it known that I, WILLIAM H. I-IAnMoN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and use ful Improvements in 1Watch-Guards, of which the following is a specification.

The invention relates to an improvement watch guards, and particularly to a guard which is normally ineffective but which becomes erl'ective upon a pull on the watch chain to prevent removal of the watch from the pocket, the eectiveness of the guard in securing the watch in the pocket being particularly proportional to the strength of pull on the chain.

The main object of the present invention is the provision of a guard designed to be connected intermediate the watch chain and ring of the watch and normally presenting a smooth cylindrical body, the interior construction providing for the projection of pocket engaging spurs lfrom the body when the pull on the chain tending to remove the watch.

rThe invention in its preferred form of details will be described in the following speciiication, reference being had particularly to the accompanying drawings, in which p Figure l is an enlarged vertical sectional view partly in elevation illustrating the prefer-red form of the improvement. F ig. 2 is a similar view of a slightly inodiiied form.

Referring particularly to the accompanying drawings, the improved watch guard comprises a cylindrical body l closed at the ends and preferably of small ornamental type. One end of the body is provided with a large catch 2 whereby the guard will be connected to the ring 3 of the watch or similar article. Movable through the opposite end of the body is a rod 4 to the inner end of which is secured a disk 5 connected by a coil spring 6 with that end of the body connected to the ring. The rod a extends through the upper or outer end of the body and is provided with a catch 7 for the connection of an ordinary chain 8 thereto. Holding spurs 9 are connected, to the disk 5 and aline with openings l0 formed in the upper end of the body as shown. The ends of the spurs 9 are preferably pointed or may be otherwise formed to readily grip or pierce the cloth of the pocket.

In the new type just described, it will be noted that one end of the spring 6 is con- Speccation of Letters Patent.

nected directly to the catch 2 thereby providing a simple and effective connection for both the catch and spring and eliminating the necessity of independent connection for each. In the operation of this type of device it will be obvious that so long as no pull is upon the chain 8 the spur or sharpened ends of thespurs 9 will be retracted within the body l hence said body presents a smooth exterior and will in no manner interfere Vwith the removal of the watch from the pocket providing said watch is removed by direct handling of the watch in the usual manner. In the event however, that attempt is made to remove the watch by a pull on the chain, as is usually the case in unauthorized removal of the watch, said pull draws upon the rod 4f and through the medium of the disk 5 will project the spurs 9 beyond the body and cause their points to pierce the walls of the pocket and effectively preu vent removal of the watch. It will be noted that the rods 9 are disposed on angularly related lines and hence the stronger pull upon the chain the greater the projection of the rods 9 and the greater the spacing of other spur ends, therefore the stronger the pull upon the chain the more effective the guard becomes. Uponv release of the pull upon the chain a spring 6 operates to withdraw the rods 9 to inoperative position, that is the housing of their spur ends within the body.

In Fig. 2 I have shown a slightly modied form of body 11 formed at one end at 12 for connection with the watch and is provided with a rod 13 slidably mounted in the body and formed at one end 14: beyond the body for connection with the chain. A disk 15 is carried by the rod 13 within the body, the spring 16 in this instance being arranged between the disk and that end of the body approached by the disk in pull upon the chain or in other words, oppositely arranged with respect to the spring in the preferred form. In the modilied form the disk l5 carries a pointed or spur end rod 17 designed to pass through openings 18 in the side wall of the body approximately intermediate the ends thereof. This form is serviceable in those instances where the watch chain extends across the person while the preferred form is more readily serviceable in those instances where the watch chain hangs vertically as in a fob or the usual lapel chain. The operation of the modied form is obvious :from the description of the preferred form.

It is of course tobe understood that the guard is comparatively lsmall and that its exterior may be plain or ornamental as desired and constructed of any metal though the usual precious metals are preferred. The metal parts of the device may be and preferably are constructed of steel, though I contemplate the use of any appropriate material for this purpose.

What is claimed isz- A Watch guard comprising a hollow cylindrical body adapted to be removably secured to the article protected and provided with closed ends, one of said ends being provided With a plurality of apertures, a rod sldablyv mounted in the apertured end and having' one end extending into the interior Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents,

of the body, a disk carried by the inner end of the rod and provided With spurs alined with the apertures in the mentioned head and adapted to be projected through said apertures When the disk is moved in one direction, a catch carried by theV other end and extendinginto the interior of .the cy-V lindrical body, and a spring interposed between the disk of the last mentioned end and having one end connected to the disk andl its opposite end connected to said catch, as and for the purpose speciied.V

In testimony whereof I aHiX my signature in presence of two witnesses. Y
